Question

what is the formula for retardation​

Answer 1

Retardation is negative acceleration.

So its formula is same as of acceleration.

$a = \frac{v - u}{t}$

Just while writing answers write minus(-) before the magnitude.

(The SI Unit is also the same for both

${ms}^{ - 2}$

)

(NOTE THAT : If the acceleration is of 2 m/s the retardation is of - 2 m/s but if the retardation is of 2 m/s, the acceleration is of - 2 m/s)

Answer 2

Answer:

retardation is also known as negative acceleration, so the formula will be same i.e

change in velocity / time
